It might be fair for other System V people to qualify the above statement
with "Historic System V" (personally I felt that Solaris without xpg4 was
unusable, and I wish you luck tackling it).

More seriously, you would need to disable "when grepping work-tree,
running the native grep is faster and just as capable" optimization in
builtin-grep.c::grep_cache().  Treat these problematic System V platforms
as if they are not __unix__.

I am surprised that you did not have issues with "tail -n$number".
Historic way to spell it was "tail -$number" wasn't it?
